Make sure to use a clean source directory after a failed build: either check out a new clone with git or remove the "build" directory and all *.md5 files in the skimage source directories. Christoph

Installing dev6.0 on windows with enthought python
by Dirk Colbry 11 Jun '12

11 Jun '12

I am struggling compiling the development version of scikits-image in Windows with Enthought Python (version 27). I need the latest version because our research team would like to try out the template matching examples. I started by using easy_install but that just provides for me the latest stable version 0.5 (not surprising). I then tried tried downloading the source as described on the website. git clone http://github.com/scikits-image/scikits-image.git cd scikits-image/ python setup.py install The above worked fine on my Mac. However, when I tried the same command on a couple of different windows7 machines everything works until I run the python setup.py install command. It looks like it is working but then it stops with the following: python setup.py install ... compile options: '-IC:\Python27\lib\site-packages\numpy\core\include -IC:\Python 27\lib\site-packages\numpy\core\include -IC:\Python27\include -IC:\Python27\PC - c' gcc -g -DDEBUG -DMS_WIN64 -O0 -Wall -Wstrict-prototypes -IC:\Python27\lib\site-p ackages\numpy\core\include -IC:\Python27\lib\site-packages\numpy\core\include -I C:\Python27\include -IC:\Python27\PC -c _spath.c -o build\temp.win-amd64-2.7\Rel ease\_spath.o Found executable C:\Python27\Scripts\gcc.exe gcc.exe: _spath.c: No such file or directory gcc.exe: no input files error: Command "gcc -g -DDEBUG -DMS_WIN64 -O0 -Wall -Wstrict-prototypes -IC:\Pyt hon27\lib\site-packages\numpy\core\include -IC:\Python27\lib\site-packages\numpy \core\include -IC:\Python27\include -IC:\Python27\PC -c _spath.c -o build\temp.w in-amd64-2.7\Release\_spath.o" failed with exit status 1 I have the latest version of enthought python installed on all of the machines. I did some searching for _spath.c and scikits-image. There where a few posts but I could not find anything related to version 6.0 of scikits-image. The following are a few links I found that looked promising: https://github.com/stefanv/scikits.image/issues/23 http://blog.philippklaus.de/2011/08/handle-16bit-tiff-images-in-python/ However, none of the links I found tell me what the problem is and how to fix it. The first link above, seems to indicate that the problem is in Cython but I am not sure how to tell if Cython is working (and I am not convinced that this is the problem). The person writing in on the second link seems to have a solution but I can't figure out what the solution is or how to reproduce it. Anyone have any suggestions on what we can try? Thanks, - Dirk

Of the pending PRs, I'd say we should aim to merge the following: * PR #195 to fix a test error (Can you confirm this error?
